What are the Advantages of infrared spectroscopy?

Answer 1

IR Advantages:

Low power requirements: therefore ideal for laptops, telephones, personal digital assistants

Low circuitry costs: $2-$5 for the entire coding/decoding circuitry

Simple circuitry: no special or proprietary hardware is required, can be incorporated into the integrated circuit of a product

Higher security: directionality of the beam helps ensure that data isn't leaked or spilled to nearby devices as it's transmitted

Portable

Few international regulatory constraints: IrDA (Infrared Data Association) functional devices will ideally be usable by international travelers, no matter where they may be

High noise immunity: not as likely to have interference from signals from other devices

Answer 2

It needs a direct line of sight between the transmitter and receiver. For example, it doesn't work through walls or doors. Also if there isn't a micro-controller in the circuit sometimes the infra red receiver has problems detecting the source of the signal.

Answer 3

There are many advantages of infrared spectroscopy. This type of method is cheaper and less time consuming to conduct. It also provides more accurate results.
